Structural composition of tubular heat exchanger

A tubular heat exchanger consists of a tube bundle, tube sheet, shell, head, baffle, etc. The two ends of the tube bundle are fixed on the tube plate, and the tube can be expanded or welded on the tube plate. The tube bundle is placed inside the tube shell, with heads added at both ends and fixed with flanges. One type of fluid flows through the inside of the tube, while the other type flows through the outside of the tube. The space between the two heads and the tube plate is used for distributing and collecting the fluid inside the tube. Two fluids exchange heat through the pipe wall.

The passage and the connecting part of the fluid passing through the heat exchange tube are called the tube pass; The passage through which the fluid flows outside the heat exchange tube and the part that communicates with it is called the shell side.

The above is the structural composition of a tubular heat exchanger.
